Portable Line Boring Machine The DIG-DOG Portable Boring Machine is a revolutionary piece of portable processing equipment designed specifically for on-site maintenance of construction machinery. Primarily, it is used for machining small pipe inner holes and concentric spacing holes. Its extensive application includes maintenance tasks for machinery like excavators, cranes, and loaders, effectively reducing equipment maintenance costs and significantly improving efficiency.
Main Application: This machine is ideal for machining revolving holes, articulated holes, and shaft pin holes on various engineering machinery structures after repair welding or reaming. It also excels in repairing and processing concentric holes, with one-time positioning for porous structures on excavators, loaders, presses, cranes, and more, ensuring perfect coaxiality.

What size of line boring machine should I choose?
There are several sizes of line boring machines available, each tailored for specific job types. No single machine can accurately cover all diameters, so it's essential to consider the types of jobs you'll be performing.
What boring bar length should I specify?
The length of the boring bar you need depends largely on your specific job requirements. Note: For small diameter boring bars, increased length can lead to a higher risk of sagging.
What are the lead times for line boring machine?
Lead times vary based on the machine's size and stock availability. It is advisable to plan ahead, as it can take several weeks from the receipt of payment for your machine to arrive. Each machine package is custom-made from a variety of available options.
Can DIG-DOG supply a machine in my area?
Yes, our portable boring machines are exported worldwide.
What maintenance is needed?
With proper care, the line boring machine will deliver years of reliable, accurate, and consistent performance. Maintenance primarily involves simple cleaning, debris removal, and regular oiling.
